hand-operatedA bolt 6` which passesthrough.

said top 2v and intov a threaded opening formed in the plate v4 approximately `mid l way' between the ends thereof. By this varrangement the hand bolt 6 will clamp the plate 4 tightly against the top 2l and the dowels 5 will overcome any tendency vof said plate to'v swing in an .arc of a circle about said bolt 6.

Y Located on the upper face ofi the plate 4 isi a iberYsheet-Lsaidv ber sheet being interposed betwen saidplate 4l and` aguide member' 8. Screws 9 pass through said guide member and said fiber sheet and into said plate 4 whereby said guidev member andsaid 'fiber sheetk are rigidly fixed to. the. top 2;, Ilt

may be mentioned here that the guideimemoer Sfserves as a stop to regulate' the position. -of'the work being acted. on by the machine, andas said guide member is shaped to correspond tothev contour of` said work, it is necessary, whenthe shapesof the parte being acted on are changed, to change" the By removing the bolt 6 the plate' 4, fiber sheet7` and guide member 8 *ma-y: betrem'o've'd'` as one unit and' replaced by ai similar"V unit having a guide ,member of the desired shape.

Secured tothe top' 2 adjacent' to the plate 4 isza plate 10,l said plate 10 supportinga fiber sheet 11 similar toA the fiber sheet 7. rEhe liber sheet' 11,. comprises the means-for supporting the Work. before 'same' is moved into position against the' guide member` 8,

said' iberslieets 7f and 11 being in the same i horizontal plane whereby said worl maybe placed ,on vthe sheet' 1l and moved! into position` againstsaidr guide member.

Located` above the plate 4 is a movable Y head l2' adapted-Atoimove'rverticallyf onafp'air Vof vertical guideV rods 13 extending rup.-

wardly from the top 2,'said guide rods eX- tending. through openings 12 in said head.

The means for imparting verticalv movement to the head 12 comprises a pair of rods 14 which entend through openings in the top Ymits 16 at the upper ends oi said rods 111-.

llhus it is apparentr that tension of the `springs l5 may be increased or decreased by the adjustment vertically of the nuts 16 whereby the pressure applied to the work is regulated. y Y s rlhe lower end portions of the rods 14 eXd tend below the top 2 and said lower ends are connected together by means ot' a rod 17.

Rotatably mounted in suitable bearings forming parts of the base 1V is a drive shaft 18 provided with a pulley 19 whereby said shaii't may be rotated to actuate the moving parts of the machine, said drive shaft being provided with a clutch mechanism which will be hereinafter described, whereby Vthe operation oi said drive shaft may. be controlled by the operator ot the machine." f

Supported by lugs 29 extending down- `wardly from the lowericaceot the top 2 is la pivoted nember 21, the` forward end of which is provided with an. opening through which the connecting rod 1.7 passes. The rear end of the pivoted4 member 21 is bifurcated as shown at- 21. Mounted onfthe drive shaft 18 in such position as to rotate between the prongs of the bifurcated end of the pivoted member, 21A is a cam 22, said cam being fixed to and adapted to rotate with said drive shaft 18.

f F rom the foregoing it is apparent that when the drive shaft 18 rotated, the cani l22 acting on thebifurcated .end 21 of the 'pivoted member 21 will cause the oppositevend .thereof to move upwardly and downwardly, and because the head 12 is connected to the outer end ot said pivoted mei lher 21 by means of the rods le and the connecting rod 17, said head will likewise be moved upwardly anddownwardly.

Fixed to the under side of the nead a2 is a `head 12 aermits the read Y removal of said plate when it is desired toreplace same with a plate designed to operate on a diii'erently shaped shoe part.

Secured to the top 2 ofY the base of the machine at the ends of the plate 10 are grooved guideways23 which receive a guardv 27 in the form 'of a comparatively heavy sheet ot glass. rlhe grooves in said gnidewaysterminate at the point indicated by the reference` character 27 whereby a space between the" lower edge of the guardy 2'? and the top face vel thefiber sheet 11 is maintained which isV high enough to permit the operatorto pass the work therethrough to the marking mechanism ot the machine, but kwill not admit'the ting-ers oi` he operator, whereby the danger of said operators lingers Vcoming into contact with the piercing pins 24 is eliminated. The guard is rmade of glass so as not to'interfere with the operators view of the work- .ing parts ot the machine.

The clutch mechanism whereby lthe `operator may control the Voperation of the machine comprises an extension- 28 Vformed on the pulley 19, said extension being provided with an annular groove 29 within which an integral lug 30 is4 located. Thepulley: 19 and the extension 28 are loosely mounted on the drive shaft 18. YFixed to the driveshaft adjacent to the extension 28 is a clutch meinber 81, said member 31 being provided with an enlarged portion 32 in which is formed a recess 32 into which the extension 28 prof liects. 'The clutch member 31V is .provided with a pivoted memberf provided with an end 33 adapted Vto engage the lug 30,-the end rof said pivoted member opposite to thelugf engaging end being acted upon by a spring Se@ which tends to throw the` lug-engaging end33 of said pivoted member into engage- Vment with said lug 30. n l

Located above the clutch 'member 311s an arm Sli ivoted to the top 2v at the point Y indicated` by the4 reference character 35, said Yarmbeing providedwith a spring 34 tending, to reta-ina friction roller 36 located at an end-thereof iny contact with thepivoted member 33. Y

Located in the top 2 adjacent to anend .of the pivoted arm 34 is a guide member 37 in the form of a rod circular in crosssection, which is provided with a continuous groove 87"throughout its length, said guide being secured in an openingin said top 2 and extendingdownwardly therefrom. Mounted in the groove 37 ofthe guide member 37 is a catch 38,-saidcatchY being provided with a shoulder 38 'adapted to enpage an end portion of the pivoted arm 34:. Located within the groove 37pin the guide member 37 is a leaf spring 39,said leafy spring bearing against said catch 38 whereby same is held 1n contact with` the end of'I the pivoted Varm Sli jwhen said arm is in its uppermost position. Pivoted to the lower end of the catch 38 is a rod 40, said rod beY ing connected to a suitable foot-pedal (not shown). To prevent the catch 38 being drawn entirely from the `groove in the guide member 37 .we provide a retaining ring 41 which surrounds said guide member at a 'point adjacent to its lower" end. Thus when the catch '38 has' been drawn downwardly to the limit of its movement, the shoulder 38l will'contact with the retaining ring 41 to prevent said catch from being moved further. v

In the operation of the device, assuming that the properly shaped guide member 8 land the proper plate 23 are'in place on the machine, and the operator places a shoe part inposition against-said guide member 8. If said shoe part -be :the'left Vsection of a shoe upper, said shoe part would'be placed with its curved portion contacting with the similarly curved portion at the right vof the guide member 8, and if it be the right seci tion of a shoe upper it would be placed with its curved portion contacting With the vcurved portion at the left ofthe guide member 8. The operator would then depress a foot-pedal whereby the rod 40 is drawn downwardly and the forward end of the pivoted arm 34V would be moved downwardly by the shoulder 38', on the catch 38, thus raising the opposite end of the pivoted arm 34 against the action of the`spring`34. The ulley 19 and the extension 28 are constantly driven, and when the end of the pivoted arm 34 which is provided with the roller 36 is moved upwardly away from the member 33, the spring 34a will cause the end of said member 33 against which it bears to move outwardly, thereby causing the end 33 thereof to be engaged by the constantly rotating lug 30, whereby said member 33 and the clutch member 31- by which it is supported will be carried around by said lug, and because said clutch member 31 is secured to the drive shaft 18 said drive shaft will be likewise rotated. Upon the rotation of the shaft 18 the rods 14 will be drawn downwardly by the cam 22 acting on the pivoted member 2,1, whereby the piercing pins 24 are caused Vto perforate the shoe part in place on the machine.

The springs 15 at the upper ends of the rods 14 eliminate the necessity of regulating the stroke of the head 12 so that the piercing pins 24 will move just far enough to perforate the work, because if the rods 14 continue to move downwardly after said piercing pins had come into contact with the ber plate 7, said piercing pins would not be driven into said liber plate, as the excess movement of said head Wo-uld be taken up by said springs 15.

The function of the catch 38 is to compel a downward movement of the pivoted arm 34 .for every operation of the machine, the shoulder 38 drawing the pivoted arm 34 lpoint 35.v "passes .from beneath the shoulder 38 ytheV arm passes from beneath said shoulder due to the fact that-said arm end moves on an arc yof a circle, the `center of which is the 1When the end of the armV 34 spring 34 will return said pivoted arm to its original position, thereby disengaging the clutch. and the rod 40 with the catch 38 attached thereto will be returned to its uppermost position -by a coil spring,'whichV is not shown 'in lthe drawing butwhich may be arranged inany convenient manner, so

that when pressure is removed from the sitionjof the/work on said work support, a head movable relative to' said work support, s a marking plate provided with piercing pins removably secured to said movable head, saidy piercing pins being secured to said marking plate and being arranged in fixedv downwardly until the end of said pivoted I positions relative thereto, means for actuat-` ing said movable head and resilient means whereby said actuating means and said movable lhead are connected together.

2. A lap-marking machine comprising a work support, means for regulatingthe position of the work on said work support comprising a removable guide member, a head movable relative tosaid work support, a marking plate pro-vided with piercing pins removably secured to said movable head,

said piercing pins being secured to said marking plate and being arranged in ixed positions relative thereto, means for actuating said movable head and resilient means whereby said actuating means and said movable head are connected together.

3. A lap-marking machine comprising a base, a work support on said base a portion of which is readily removable therefrom, said removable portion of said work support being provided with a guide member for regulating the position of the work on said work support, a head movable relative toI said work support, a marking plate provided with piercing pins removably secured to said movable head, said piercing pins being secured to said marking plate and being arranged in fixed positions relative thereto, and means for actuating said movable head.
